CLAiVlPING DEVICE FOR HEDDLE-BARS OR SUPPORTS.

To all whom t may concern:

Be it known thatLI-IUMPHREYS W. J oRDAN, a citizen of the United States,and a resident of Pelzer, county of Anderson, State of South Carolina,have invented an Improvement in Clamping Devices for Heddle Bars orSupports, of which the following description, in connection with theaccompanying drawings, is a speciiication, like characters on thedrawings representing like parts.

This invention has for its object the productionA of a novel, simple,and efficient device fer locking or clamping in place the detachableharness or heddle support in a harness-frame, particularly of the typewherein the heddles serve also as warp-stop-motioncontrolling detectors.

By the means forming the subject-matter herein the heddle-support ispositively and firmly held in position, while its ready removal whendesired is also made possible.

Figure l is a front elevation, centrally broken out, of a harness-frameembodying one form of my invention, the side bars also being broken outand one of the heads being shown partly in section. Fig. 2 is a sideelevation of one of the heads with the locking device for theheddlelsupport in position. Fig. 3 is a similar view, but from theopposite side of the head,showing the longitudinal slot therein. Fig. 4.is a perspective View, enlarged and detached, of the follower; and Fig.5 is an enlarged side elevation of the follower and the locking orclamping bolt.

Referring to Fig. l, the bottom cross-bar ctx of the harness-frame hassecured to it upright side bars a, shown as rods, which are preferablythreaded at their upper ends to enter correspondingly-threadeiiA bossesb of heads b, the latter being conveniently made as castings. Each headhas a longitudinal slot b2 extended therethrough, reduced in width atits lower portion at b3 and leaving shoulders 20, (see Fig. 3,) thewalls of the portion b3 being shown in said figure as slightlyconvergent toward the bottom of the seat. A transverse pin bx crossesthe seat for a purpose to be described.. The heddle-support h, shown asa flat bar, is notched in its lower edge near each end, as at hx, Fig.1, to ennbrace the pin bx when the ends of the support are inserted inthe seats b3 to prevent any relative lateral movement of the side barsof the frame and the heddle-support when the latter is in position. Thesupport is applied by inserting its ends in the wider ends b2 of theslots, and then the heddle-support is pushed down into the seats, thenotches hx engaging the cross-pins bx, the construction so far describedbeing substantially as shown in United States Patent No. 729,047.

In order to hold the support h down inthe seats during the sheddingoperation, I have provided a follower which is slidably mounted in theupper endof the slot of each head, the follower being shown separatelyin Figs. t and 5, and, referring thereto, the bodyfof the follower isshown as a fiat plate corresponding in length to the width of one of theheads b and adapted to enter easily the part b2 of the slot, the upperand lower edges of the body being longitudinally grooved, as at f f2,respectively. At one end the body is provided with an enlarged ear f3 ina plane at'right angles to the body, this ear resting against,preferably, the outer side of the head, as shown clearly in Figs. 1 and2. The shoulders 20 prevent the follower from dropping down or becomingwedged in the portion b3 of the slot when the heddle-support is removed.The ear f3 is provided with a hole f x in alinement with the uppergrooved edge of the body f, and a clamping or locking bolt cis ex`tended through the slotef the head h and through the hole f x in the earof the follower, the bolt being supported in the groove f of the latter,as shown in Fig. 5. The head c of the bolt is nicked, as at c2, andbetween the bolt-head and the adjacent side of the head b of the frame awasher w is interposed, while a retaining-nut cx is set up on thethreaded end of the bolt projecting beyond the upper edge of saidsupport, the grooves f2 firmly engaging said upper edge, and then thenuts cx are set up, thereby firmly clamping or looking the followers tothe heads. The bolt-heads are nicked, so that a screw-driver may beemployed to prevent turning of the bolt, if necessary, when setting upthe nuts CX. When it is desired to remove the heddle-support, it is onlynecessary to slacken up the nut eX, when the operative eau slide thefollower upward far enough to permit the removal of the support.

The construction is simple, strong, an d provides a positive downholdand lock for the heddle-support.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a loom harnessframe, side bars having heads each provided with alongitudinal slot, a detachable heddle-support adapted to be seated atits ends in the slotted heads, a follower on each head and slidable inthe slot. thereof, to engage the edge of and hold the heddle-support inposition, and a locking-bolt mounted on and to elampthe followeron thehead.

2. In a loom harness-frame, side bars hav ing heads each provided with alongitudinal slotwidened atits upperend,a detachable heddle-supportadapted to he seated at its ends in the lower end of each slot, afollower movable in the widened end of the slot and adapted to engagethe upper edge of and position the heddle-support when seated, and aclampingbolt carried by eaoh follower and adapted to cooperate with thehead and lock the follower from movement.

3. In a loom harness-frame, side bars having heads each provided with alongitudinal slot, a detachable heddle-support adapted to be seated atits ends in the bottoms of the slots, means to prevent lateral movementof The heads when said support is in place, a follower slidable in eachslot and having an external, transverse ear, and a clamping-bolt carriedby the ear and extended through the slot to engage the opposite side ofthe head, to lock the follower from movement when in engagement with theupper edge of the heddle-support.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
